They MUST NOT be used at the same time for the same text analysis target/node." This is also reflected in the RELAX NG schema - you would get a valiadation error its-ta-source and its-ta-ident-ref appearing at the same element. So the question is whether this should be relaxed to "Mode 1 and mode 2 are mutually exclusive. They SHOULD NOT be used at the same time for the same text analysis target/node." and the schema should be lax here and not throw an error?
